[0031] In order to better understand the technical solution of the present utility model, the embodiments provided by the present utility model are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-2 As shown, it can be understood that a cat litter box provided in the present embodiment comprises: a shell 1, a litter box 2 is arranged in the shell 1, and a scraper 4 is arranged above the litter box 2; a slide rail 3 is also arranged on the shell, a trolley 5 can slide on the slide rail 3, and the scraper 4 is rotatably connected to the trolley 5; the slide rail 3 and the bottom of the litter box 2 are both arc-shaped, and the bending curvature is the same and the position corresponds; a torsion structure is provided at the rotation connection between the scraper 4 and the trolley 5; a first limiting wall 100 is provided at one end of the scraper 4, and a second limiting wall 51 is provided on the trolley, and during the rotation of the scraper 4 relative to the trolley 5, the first limiting wall 100 can abut against the second limiting wall 51; the direction in which the first limiting wall 100 abuts against the second limiting wall 51 is opposite to the torsion direction of the torsion structure.

[0033] In this embodiment, the litter box 2 is used to hold cat litter, and the shovel blade 4 is used to scoop out cat feces after the cat urinates and defecates; the special feature is that a slide rail 3 is provided on the housing 1 to guide the sliding of the trolley 5, and the sliding of the trolley 5 drives the shovel blade 4 connected thereto to move, thereby realizing the cleaning of cat feces. In this embodiment, the bottom of the litter box 2 is designed to be an arc shape that is convenient for the shovel blade 4 to fit, so that when the shovel blade 4 is working, the shovel blade 4 can fit the bottom of the litter box 2 throughout the entire process; in order to make the shovel blade 4 fit completely to the bottom of the cat litter box, the slide rail 3 that drives the trolley 5 to move is also designed to be a corresponding arc shape, so that the shoveling angle of the shovel blade 4 is exactly the same when shoveling, and the shovel blade 4 fits completely.

[0034] In addition, if Figure 2As shown, the torsion structure is like a torsion spring, which can realize the tip of the shovel blade 4 to be pressed downward by torsion, so that the shovel blade fits closely with the bottom of the litter box during the forward movement, so as to remove cat feces as much as possible; on the other hand, a first limiting wall 100 is provided above the shovel blade 4, and a second limiting wall 51 is provided on the driving vehicle 5. The shovel blade 4 will return to the starting position after shoveling cat feces. During the return process, the shovel blade 4 will rotate upward due to the force of the cat litter in the litter box, but due to the conflict between the first limiting wall 100 and the second limiting wall 51, the shovel blade 4 cannot rotate upward without limit. The conflicting pressure between the first limiting wall 100 and the second limiting wall 51 causes the end of the shovel blade 4 to be pressed downward, and the cat litter can be pressed flat during the process of the shovel blade 4 returning to the starting point. Then the torsion structure shovels the cat feces cleanly, and the conflict between the first limiting wall 100 and the second limiting wall 51 ensures the flatness of the cat litter.

[0035] Furthermore, a toilet bowl 6 is provided at one end of the sand basin 2, and the shovel 4 can slide back and forth toward the toilet bowl 6 through the slide rail 3; a rotatably connected toilet bowl cover 7 is provided on the toilet bowl 6, and the opening direction and connection direction of the toilet bowl cover 7 and the toilet bowl 6 are opposite.

[0036] The toilet 6 is provided with a rotatably connected toilet cover 7, and the opening direction and connection direction of the toilet cover 7 and the toilet 6 are opposite. The toilet cover 7 can be used to close the toilet 6 to prevent odor from overflowing. The toilet cover 7 is rotatably connected to the toilet 6, and its opening is opposite to the connection, which is convenient for opening.

[0037] Furthermore, the opening is connected to the litter box 2, and the shovel blade 4 faces the opening direction, and the end of the shovel blade 4 fits the litter box 2. The opening between the toilet cover 7 and the toilet bowl 6 is connected to the litter box 2, which is convenient for the shovel blade 4 to directly shovel cat feces from the litter box 2 to the toilet bowl 6. The end of the shovel blade 4 fits the bottom of the litter box 2, and the cat feces can be cleaned as much as possible.

[0038] On the basis of the above embodiment, a rack 8 is provided on at least one side of the slide rail 3, and a gear 9 is provided at the junction of the trolley 5 and the slide rail 3, and the gear 9 is meshed with the rack 8. By setting the meshing of the rack 8 and the gear 9, it can be ensured that the trolley 5 slides evenly on the slide rail 3.

[0039] In addition, if Figure 2-3 As shown, the blade 4 includes a tool holder 10, which is movably connected to the trolley 5 through the tool holder 10; the first limiting wall 100 is set on the tool holder 10; the blade 4 is detachably connected to the tool holder 10. In this embodiment, a tool holder 10 is designed on the blade 4, and the tool holder 10 is axially connected to the trolley 5 at the top and connected to the blade 4 at the bottom. There is a locking structure between the blade holder 4 and the blade 4, so that the user can replace or clean the blade 4 through the locking structure.

[0040] In this embodiment, the scraper 4 includes a mesh blade surface 41 and a door opening arc wall 42, the door opening arc wall 42 is arranged on both sides of the blade surface 41, and the height is higher than the blade surface 41, and the door opening arc wall 42 can contact the toilet lid 7. The blade tip 43 of the blade surface 41 is wing-shaped.

[0041] Specifically, the mesh blade surface 41 helps to filter out the cat litter in time, and the blade tip 43 is an airfoil structure (i.e., it has a certain raised portion at the top). When working, the blade tip 43 is responsible for shoveling cat feces from the bottom, and then the shovel blade 4 moves back and forth. At this time, the cat feces will float to the surface of the cat litter, and then move forward. The cat feces will stay on the top of the raised portion, and the cat feces will not accumulate in front of the blade tip that contacts the bottom for a long time. The raised portion is higher, so during the pushing process, the cat feces will be higher than the cat litter and will not be pushed away; on the contrary, if there is no airfoil blade tip 43, the cat feces will be concentrated in front of the blade tip 43, and the excess cat litter will also be pushed away.

[0042] like Figure 5-7 As shown, when the shovel blade 4 reaches the front end of the sand basin 2, the door arc walls 42 at both ends of the shovel blade 4 will push the toilet lid 7 open, and the shovel blade 4 continues to move forward, and the toilet lid 7 will be pushed open further; Figure 5-6 As shown, after the shovel blade 4 passes over the front end of the litter box 2, the shovel blade 4 will tilt downward under the action of the torsion spring and gravity until all the cat feces are poured out.

[0043] When the shovel blade 4 is retracted, the shovel blade 4 will flatten the cat litter and return to the starting position because the upward angle of the shovel blade 4 is fixed by the first limiting wall 100 and the second limiting wall 51, and under the pressure of the torsion spring, the shovel blade 4 will return to the starting position. At this time, the toilet cover 7 will cover the toilet 6 and have a certain sealing performance to prevent the odor from leaking.

[0044] Furthermore, a disinfection device is provided below the traveling vehicle 5. An ultraviolet disinfection lamp is provided under the traveling vehicle 5, and ultraviolet disinfection is performed while shoveling feces.

[0045] In this embodiment, a circuit board, a battery and a sensing device are also provided in the housing 1, and the trolley 5, the disinfection device, the battery and the sensing device are all connected to the circuit board. A battery is provided in the machine, and the battery can be removed for charging. With such a function, the device can work independently even if it is far away from a power source. The sensing device is used to sense the position of the cat. When the sensor senses that the cat has passed, it starts to shovel cat feces after a set delay time (giving cat litter absorption time). Under the push of the trolley 5, the shovel blade 4 is pressed against the bottom of the cat litter box by the torsion spring and starts to shovel, pushing forward a certain distance, then retreating a certain distance, and so on.

[0046] The above is a detailed introduction to a cat litter box provided in an embodiment of the present invention. For a person skilled in the art, according to the idea of ​​the embodiment of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
